Algoritmo de cifrado de audio digital mediante atractores caóticos

Abstract

The transfer of multimedia files such as audio files is a fairly common problem today, therefore it is the subject of research in fields associated with information security. In the following project, an encryption system for digital audio is defined and developed using different non-linear dynamic systems, taking advantage of their chaotic characteristics to confuse and spread the processed audio signal. For this purpose, two pseudo-random number generators were built from the attractors defined by the Store and Logistics function, which are used for the audio diffusion process, and another generator was created using Chebyshev polynomials for the confusion process. The proposed algorithm was put to the test by applying a wide variety of tests that sought to confirm high levels of security and performance.
